  3. 4. where the land meets the sea
  4. 5. An artificial barrier constructed across a river to hold back water and raise its level, forming a reservoir used to generate electricity or as a water supply.
  5. 8. the act or practice of cultivating land to an excessive degree in the growing of crops so that soil quality is degraded and productivity is reduced.
  6. 10. the ability to be maintained at a certain rate or level.
  7. 11. A measure of human demand of the earth’s natural systems
  8. 12. Increased ability of the Earth’s atmosphere to trap heat. An observable rising trend in the Earth’s atmospheric temperatures, generally attributed to the enhanced greenhouse effect.
